Geologists Researchers using Google Earth detected some characteristics (chevrons) of a Giant Tsunami in the Indian Ocean. They analyzed the satellite images of the area’s bottom morphology and there was a huge crater. It is now believed that when this crater was created, a tsunami of 200m height hit the area and it was raining all over the world for days. They estimated the age of the crater at 5000 years.

I'd love to know more about how they reached this particular conclusion.

They used The Internet Archive's "Wayback Machine" feature to look at previous versions of Google Earth, of course...

LOL. (And I don't type LOL or actually LOL when browsing the internet all that often ;-) ).

The explanation is obvious to some scientists. A large asteroid or comet, the kind that could kill a quarter of the world’s population, smashed into the Indian Ocean 4,800 years ago, producing a tsunami at least 600 feet high, about 13 times as big as the one that inundated Indonesia nearly two years ago. The wave carried the huge deposits of sediment to land.

Hardly a confirmation that it was raining all over the world for days. That's the particular part of the quote that makes me wrinkle up my forehead.

An asteroid strike in the ocean would release a huge amount of heat into the water, evaporating plenty and causing storms everywhere. 40 days and 40 nights might be a reasonable estimate.
